I My. invention relates to. a doubleacting auxiliary clutch, and has for one objectto provide a new and improved form of clutch control mechanism whereby positive me"- chani'cally; operated means under the control of the operator areprovidedt'o enable the operator by mechanical means quite independent of his own strength, to operate a clutch; My invention'is especially adapted for use in connection with the type of clutch where substantially as much force is required to disengageas to engage the clutch.

Among the obj ects of my invention, then, are to provide power controlled means for engaging and disengaging a clutch or other mechanism, toprovide such means wherein the degree of engagement or disengagement isiat all times controlled by the operator, to provide a clutch contr olmechanis'm wherein the operation during the entire'engagingand disengaging cycle 1s under the positive control of the operator but is altogether inde:

pendent of the strength which the operator himself is ableto apply to the work.

.My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein Figure 1' isfa plan view;

It will be especially obviousthat where I have shown my auxiliary clutch or driving mechanism applied to the actuation ofa main clutch, that such actuating mechanism might be equally well applied to any other situation where such anactuating device is-appropriate. H

The use and operationof my invention are as follows: I v

With the parts in the position shown in the drawings,thefloating linkD? is vertical. The lever D is in the neutral position and the double cone is in the separate position and nothing happens. a v V r V If, now,- the'operator moves his hand lever forward-he draws the floating lever at its lower end towards the left, rotating the screw in a counter clockwise direction. This pulls out on the double cone, causes the right hand combined bevelled'gear and cone to rotate and, depending upon the direction of the rotation of the shaft A, rotates the power lever D to positively rotate the clutch operating lever. But because the power lever and the clutch operating lever are'tied up by means of the bell crank lever and the sliding shaft with the fulcrum of thefloating link,

the fulcrum moves forward tending to restore the. floating link to. the: vertical position, and tending to throw the vauxiliary clutch out. Aslong as theoperator continues to press forward on his, hand lever this movement of the fulcrum of the floating lever. is

I prevented or compensatedfor, and the auxiliary clutch remains in. As soon as the operatorstops movement of his lever, the mechanism catches up, the floating link becomes vertical, and the auxiliary clutch disengages. Movement in the opposite direction, is caused by opposite manipulation of the hand lever back to the starting position, and if desired, beyond it in the reverse direction.

It will be noted thus, that the hand lever merely serves to control the power; that the effect on the main clutch of the strength of the operator is absent or at least negligible, and the auxiliary clutch deliverspower to operate the mainclutch in either direction under controlled'conditions bythe hand of the operator.
